We released in the last finals the "retro challenge", no laptop, just piece of paper and pen, with assembly to decoded manually, turns out to be the more fun one for everyone And we also embrace AI instead of blocking it turn in the CTF into an agentic one

From BSides Querétaro → CCWD 🇲🇽🔥 Congrats to Fernando Romero! A red teamer who took on malware analysis and reverse engineering until he “lost the fear of it.” And we’re proud to support the @BSidesQueretaro CTF. Same philosophy: learn by doing 💚 #CCWD #BSidesQueretaro #CTF

There’s a difference between finishing a course and coming out of it more dangerous to malware. 🦠 Hinkul Maksym completed CCWD and, in his words, it “forced me to level up my malware analysis skills.” That’s the point. 🔥 #CCWD #MalwareAnalysis #ReverseEngineering

A recommendation opened the door. Ignacio did the rest. 🔥 Congrats to Ignacio Rey, a #TecdeMonterrey student and now a #CCWD Recommended by his professor. Challenged by real #malware . Earned through hands-on work. Welcome to the crew! #MalwareAnalysis #ReverseEngineering
